In this series of step-by-step tutorials, we show you how to troubleshoot and fix common WordPress errors.
Important: Always back up your WordPress site (files and data) before modifying any files or performing any upgrades or installations!
If you don’t want to back up your files manually, then consider getting professional WordPress help, or use a WordPress backup plugin.

Normally, when you update your software, plugins, or themes, WordPress will temporarily go into “Maintenance Mode.”
What can sometimes happen when performing WordPress upgrades, especially if using automated solutions, is that WordPress can get stuck in Maintenance Mode and your site will then display a “Briefly unavailable for scheduled maintenance. Check back in a minute.” message as shown in the screenshot below instead of your regular web content …
(WordPress Stuck On “Briefly Unavailable For Scheduled Maintenance”)
More likely than not, if you find yourself in this situation, you will not be able to log into your WordPress site or access any other page of your site.
Here is a simple way to fix this problem:
Log into your server using FTP software or via cPanel > File Manager and locate a file in the root folder called “.maintenance” …
Delete this file from your server …
The “failed update” message should be removed the next time you log into your WordPress administration area, refresh your browser, or open up a new browser window and type in your site’s URL.
In addition, you should find your site restored and working again …
Sometimes, if the error happens in the middle of the WordPress software upgrade procedure, you may be presented with a “Database Update Required” dialog box like the one shown in the screenshot below …
(WordPress Database Update Required)
If the above screen comes up, just click on the Update WordPress Database button to complete the upgrade process.
You may also want to try changing the permissions of your /upgrade/ directory. WordPress uses the wp-content/upgrade/ directory to create a temporary file used during the installation process …
For the temporary WordPress file to be created, the /upgrade/ directory needs to be writable by the server. To check if this is what is causing the issue, try setting the directory permissions to 777 (or CHMOD equivalent) and retry the auto-update process.
To learn how to set server file permissions, see the tutorial below:
Note: Always use the most restrictive permissions possible for your server files. This may require a little research, experimentation and assistance from your web hosting provider, but it will ensure the security of your files and your website.
If you’re still experiencing problems or errors using the auto-update features, here are some additional configuration settings you may want to ask your web hosting company to test or check to see if your issues can be resolved:
- Safe Mode turned off
- Define FTP Variables in wp-config.php
- Server not running suPHP
